Understanding sample rate, bit depth, file formats, and dither

Part of the mastering process is eventually obtaining a stereo mix of your track in a format that is supported by mainstream playback systems. Now, whether that be a CD player, MP3 or other digital format, it is important to understand how digital audio is stored and ultimately the effect this has on the audio quality at the end of the day. So, in its uncompressed form inside of Pro Tools, digital audio exists as a finite series of discrete samples or frames where each sample is measured with a finite number of bits, ones or zeros, from the continuous analog waveform and this happens at the analog to digital converter stage.

This sampling process is known as Linear Pulse Code Modulation and the data is most commonly stored in the WAV or AIFF file formats. So, an example would be audio recorded at 44,100 times per second or 44.1K at a resolution of 24-bits is measured 44,100 times per second or 44,100 frames with each frame or sample represented by 24-bits of data.

So, the sample rate is...
